When Inflating Your Tires
When putting air into your tires (such as at a gas station or in your
garage), the tire pressure monitoring system may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn off after you have filled your tires to the recommended
inflation pressure.
How Temperature Affects Your Tire Pressure
The tire pressure monitoring system monitors tire pressure in each
pneumatic tire. While driving in a normal manner, a typical passenger
tire inflation pressure may increase about 2 to 4 psi (14 to 28 kPa) from
a cold start situation. If the vehicle is stationary overnight with the
outside temperature significantly lower than the daytime temperature,
the tire pressure may decrease approximately 3 psi (21 kPa) for a drop
of 30°F (17°C) in ambient temperature. This lower pressure value may
be detected by the tire pressure monitoring system as being significantly
lower than the recommended inflation pressure and activate the system
warning light for low tire pressure. If the low tire pressure warning light
is on, visually check each tire to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check the air pressure in the road
tires. If any tire is under-inflated, carefully drive the vehicle to the
nearest location where air can be added to the tires. Inflate all the tires
to the recommended inflation pressure.
CHANGING A ROAD WHEEL
WARNING: The use of tire sealants may damage your tire
pressure monitoring system and should not be used. However,
if you must use a sealant, have an authorized dealer install a new tire
pressure monitoring system sensor and valve stem.
WARNING: See Tire Pressure Monitoring System in this
chapter for important information. If the tire pressure monitoring
sensor becomes damaged, it will no longer function.
Note: The tire pressure monitoring system indicator light will illuminate
when the spare tire is in use. To restore the full function of the monitoring
system, all road wheels equipped with tire pressure monitoring sensors
must be mounted on this vehicle.
